Definitions
- the invention relates to a vapor deposition material for the production of highly refractive optical Layers of titanium oxide, titanium and lanthanum oxide in a vacuum and a process for Production of the vapor deposition material.
- Oxide layers are widely used in technology, especially in optics used as protective layers or for optical functional purposes. They serve as Protection against corrosion and mechanical damage or to compensate for the Surfaces of optical components and instruments, such as lenses, mirrors, prisms, Lenses and the like. Furthermore, the oxide layers are used for manufacturing high, medium and low refractive index optical layers to increase reflection or reduction used.
- the main areas of application are Production of anti-reflective and coating layers on spectacle lenses and on Lenses for camera lenses, for binoculars and optical components for optical Components and for laser technology. Manufacturing is another application of layers with a certain refractive index and / or certain optical Absorption properties, for example for interference mirrors, beam splitters, Heat filters and cold light mirrors.
- DE 42 08 811 A1 discloses a vapor deposition material for producing highly refractive optical layers by vapor deposition of substrates in a vacuum.
- it is a compound of the formula La 2 Ti 2 O 6.5 .
- Such vapor deposition materials are produced in such a way that oxides of lanthanum and titanium as well as metallic titanium are mixed in the appropriate stoichiometric ratio and sintered in a high vacuum below the melting temperature.
- From DE-PS 1 228 489 is a method for producing thin, in the visible Wavelength range of practically absorption-free oxide layers for optical purposes in particular on substrates made of glass, by vapor deposition of oxidic and / or oxidizable substances known in vacuum. The evaporation can if necessary take place in the presence of an oxidizing atmosphere.
- the oxidic and / or oxidizable substances are one or more elements and / or Rare earth oxides including yttrium, lanthanum and cerium evaporated.
- the starting substances are evaporated as a mixture or evaporated separately.
- oxidic and / or oxidizable substances Among others, titanium and / or titanium oxide are used.
- the selection is suitable Limited raw materials. Essentially come as starting materials for this the oxides of titanium, zirconium, hafnium and tantalum as well as mixed systems thereof in Consideration.
- a preferred starting material for high refractive index layers is Titanium dioxide.
- titanium oxide In addition to titanium oxide, compounds such as Tantalum oxide, zirconium oxide, hafnium oxide and zinc sulfide and mixtures of oxides for example zirconium oxide and titanium oxide, titanium oxide and praseodymium oxide and titanium oxide and lanthanum oxide for use.
- compounds such as Tantalum oxide, zirconium oxide, hafnium oxide and zinc sulfide and mixtures of oxides for example zirconium oxide and titanium oxide, titanium oxide and praseodymium oxide and titanium oxide and lanthanum oxide for use.
- titanium dioxide has a high refractive index and hafnium and zirconium dioxide have low absorption.
- Disadvantages of these known substances are strong outgassing and spraying of the titanium dioxides, relatively high absorption with tantalum oxide Ta 2 O 5 , with a mixture of titanium oxide and praseodymium oxide and incomplete melting of zirconium oxide, hafnium dioxide and a mixture of zirconium oxide and titanium oxide, but also low hardness such as, for example with zinc sulfide.
- a mixture of titanium oxide and lanthanum oxide With a mixture of titanium oxide and lanthanum oxide, the advantages of low absorption, no outgassing and no splashing and relatively good melting down are achieved.
- the refractive index of such a mixture is significantly lower than that of titanium dioxide and zinc sulfide. From a practical processing point of view, it is also disadvantageous that these substances have high melting and boiling points, which are also relatively close to one another. In order to ensure an even and sufficient evaporation rate, it is necessary that the evaporation materials are completely melted down before the start of a noticeable evaporation. This condition is necessary so that homogeneous and uniformly thick layers can form on the objects to be steamed. However, this is not the case with the oxides of zircon and hafnium and with titanium-zirconium mixed oxide systems under practical conditions of use.
- the object of the invention is to provide a vapor deposition material of the type described in the introduction provide from which optical layers with the highest possible Refractive index and low absorption can be produced, the Evaporation material shows a very good melting and evaporation behavior and can be evaporated practically without outgassing and spraying.
- the mixture contains 19 to 65% by weight of lanthanum oxide, 38 to 74% by weight of titanium oxide and 2 to 7% by weight of titanium.
- the mixture consists of 58.9% by weight of lanthanum oxide, 37.9% by weight Titanium oxide and 3.2% by weight titanium.
- An embodiment is also provided for which is the mixture of 63.2% by weight of lanthanum oxide, 33.9% by weight of titanium oxide and 2.9 % By weight of titanium.
- the weight ratio of titanium to lanthanum oxide can be determined by adding lanthanum oxide to the mixture of titanium oxide and titanium. Sintering in a vacuum ensures that the stoichiometry of the mixture with respect to the oxygen does not change.
- the vapor deposition materials according to the invention have an oxygen deficit compared to the stoichiometrically exactly composed basic compound lanthanum titanate within the scope of the formula definition mentioned above.
- the selected range of the oxygen deficit is such that under the usual working conditions in vacuum evaporation technology, absorption-free layers are easily formed. Studies have shown that even a relatively small addition of lanthanum oxide can improve the behavior during melting and evaporation.
- the mixture according to the invention can be melted and evaporated in an electron beam evaporator device practically without spraying and without outgassing by setting an optimal stoichiometry with respect to oxygen.
- the refractive index of layers which are produced using the vapor deposition material according to the invention is only slightly lower than that of pure titanium oxide layers.
- the refractive index is significantly higher than in layers made of tantalum oxide, zirconium oxide, hafnium oxide or mixtures of oxides such as zirconium oxide and titanium oxide, titanium oxide and praseodymium oxide and titanium oxide and lanthanum oxide.
- the good melting behavior makes it possible to set and maintain a flat melting surface for the evaporation of the vapor deposition material. As a result, a uniform, reproducible layer thickness distribution can then be set on the substrates to be coated. This is very difficult, if at all possible, in particular when using materials that melt more poorly, such as hafnium oxide, zirconium oxide, a mixture of zirconium oxide and titanium oxide.
- sintering is carried out in a vacuum of 1 * 10 -4 mbar at a temperature of 1500 to 1600 ° C. over a period of 51 ⁇ 2 to 61 ⁇ 2 hours.
- a method is to be provided which makes it possible to produce optical layers with a high refractive index and extensive freedom from absorption from the vapor deposition materials. This is done in such a way that the substrates to be coated are cleaned, dried, attached to a substrate holding device in a vapor deposition system, that the vapor deposition system is evacuated to 1 * 10 -5 mbar, the substrates are heated to 280 to 310 ° C, that oxygen is in the The evaporation system is let in until a pressure of 1 to 2 * 10 -4 mbar is reached, that the evaporation material is melted in an electron beam evaporator device of the evaporation system, which is closed off by a panel, and heated to its evaporation temperature from 2200 to 2300 ° C and that after opening the panel, the Substrates are coated with the vapor deposition material up to a predetermined thickness.
- Such optical layers are widely used and used as Anti-reflective and coating layers on glasses, lenses for optical Instruments, optical components for laser technology and as layers with predetermined high refractive index and / or optical Absorption properties for beam splitters, interference mirrors, cold light mirrors and Heat filter.
- the vapor deposition materials according to the invention can be used on suitable substrates homogeneous thin layers of uniform layer thickness are created that are adherent and particularly resistant to mechanical and chemical influences are.
- these layers are highly refractive, and have in the generally high transmission in a wavelength range of close to UV, that is at a wavelength of 360 nm over the visible range up to the near infrared at a wavelength of approx. 7000 nm. In the visible In the wavelength range, these optical layers are largely free of absorption.
- a mixture of 58.9% by weight of lanthanum oxide, 37.9% by weight of titanium oxide and 3.2% by weight Titan is mixed homogeneously, granulated to a grain size of about 1 - 4 mm and sintered in vacuo at about 1500 ° C for 6 hours.
- the sintered product is deep black.
- the sintered product is filled into a molybdenum crucible of a vapor deposition system and used in the electron beam evaporator device of the system.
- the substrates to be coated such as disks made of quartz glass with a diameter of 25 mm and a thickness of 1 mm, are cleaned and dried and attached to a substrate holding device in the evaporation system.
- the vapor deposition system is a system known in the prior art, which is neither shown in the drawing nor described in detail. After evacuation to a pressure of 1 * 10 -5 mbar, the substrates are heated to a temperature of about 300 ° C.
- oxygen is admitted into the evaporation system via a regulating valve until a pressure of 1 to 2 * 10 -4 mbar is reached.
